250296-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 250296-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,2,9 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 250296-57:
(8*2)+(7*5)+(6*0)+(5*2)+(4*9)+(3*6)+(2*5)+(1*7)=132
132 % 10 = 2
So 250296-57-2 is a valid CAS Registry Number.
